ASK Proxima C420 shuts down after 30 seconds. No indication of overheating or lamp problem.

Might be a problem with the video input. Try a different cable. If HDMI, you will need a really good cable for HDTV or 3D, and they are very expensive. My 12 foot cable cost $180.

JVC DLA-RS1U Projector turns off

I have a similar problem. JVC Project (DLA-RS1) shuts off after about 30 min to 1 hour of use. Everything turns off - bulb, fan, even the little light on the projector near the buttons. After 10-15 min the red light comes back on and you can start the projector.

I have seen this happen when I had installed a knock-off bulb. I believe the bulb runs a little hotter and the projector over heats. Now I am seeing it happen even with a JVC bulb.

I am in the process of taking the cover off the projector to see if anything is blocking the air flow (like a piece of broken bulb, which did break a while back). If a problem doesn't show up there I am going to check the fan to see if it is turning at full speed (maybe replace with a beefier fan?).

Does anyone have instruction on dis-assembly?

Dell 3200MP projector. Lamp warning light comes on after approx 30 minutes of use and the lamp turns off. Bulb is new. I am not sure what the warning light is indicating.

The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work
get a small fan and place it near the projector to provide
extra cooling. The projector is running border line on
high temperature and just needs a little extra cooling.

red flashing in sequence:
2 times- lamp hours exceed 200 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fans not working. remove obstruction or replace fan.
5 times- temp too high. clean thoroughly.
solid red- undiagnosed error by projector. possible power supply or ballast.

also make sure the lamp door switch is working.

My infocus IN1 projector won't turn on anymore.

It may be the lamp is out. Normally a projector will try & fire the lamp 3-5 times then shut down with a different color light like amber or red. If the lamp doesn't light then it could be the lamp or perhaps the lamp ballast that starts the lamp has failed. A stuck fan also causes similar symptoms. There's 2-4 fans in the projector if one is stuck or bad it will turn off within 5 seconds or so after the lamp lights.
Does your lamp light at all? Are the lights a different color after it shuts down? Answers to these questions help figure out what's wrong though it's impossible to say for sure without looking at it. I service almost all Infocus projectors if you would like a quote please reply with your email address or write me at
Good Luck,
